The Blue Scar Paradise fish are vibrant and active. I kept them in a planted tank with Java fern and moss. They stayed calm and didn’t attack other fish. The color is striking and they look great in the tank.

I bought one for my 50-liter tank. It’s a beautiful fish with a unique blue and silver pattern. I made sure to keep it alone and added plenty of plants. It’s active and stays in the middle to upper levels.

Great addition to my aquarium. The fish are very colorful and show off their movement well. I keep them in a planted setup with dense vegetation. They don’t stress other fish and seem happy.
